Just move the open ring around your ankle and press down on the snap to lock in place - you're ready to jump! To open the ring, simply lift up on the tab to "pop" it open. No shoes to take on-and-off like solid ring models, and therefore no wasted time at the beginning or end of class! The newly designed ring has a new "speed control" channel that allows for adjustment in the rope length. Lengthen the rope a couple of inches for slower ball rotation around the ankle; shorten the rope for faster rotation... it's as easy as changing the rope length by pressing it down into the ring chamber! Also the balls release from a connector on the end of the rope, so you in essence get 6 free balls for play when not using for jumping!
